Toward a Data Lake

Context Presentation

neOCampus is a large operation with different kinds of projects and actors. Started in 2013, its goal is to improve the university campus user’s everyday life through data analysis for people, fluid consummation reduction, reduce building environmental footprint, etc.… Overall, it tends to make the campus smarter. All those projects have one common point: data. Including images, sensor logs, administrative data, configurations, we can find every kind of data and each must be stored somewhere.

This project is centered around this problem with a data management system architecture which is the data lake.The conception of this kind of solution must include handling every kind of data and making it possible to follow the life of a data from the input to the usage in a project. It does not only have to store every kind of data, it is needed to know what is stored, where and in the proper format to use it in the easiest way. When a new data has arrived, the system will automatically rawly store it, find the more valuable format, extract information from this data and make this knowledge available for any purpose.

Study of Environmental and Socio-Economical Impacts of Lighting Systems

Context Presentation

When it comes to evaluate the quantifiable effects of products or services on the environment, Life Cycle Assessment (LCA) is probably the most efficient and recognized tool. Thanks to a “cradle to grave” approach, LCA identifies and quantifies, throughout the life of products, the physical flows of matter and energy associated with human activities (extraction of raw materials, manufacturing of the product, distribution, use, collection and disposal towards end-of-life). For each of its flows correspond impact indicators which allow to establish the overall potential impact of the system on our environment. With regard to lighting, “smart” technologies have made it possible to improve energy efficiency during use phase and thus greatly limit its impact on the environment.

Before the development of these new technologies, lighting represented 14% of European consumption and 19% of global electricity consumption (2009). Today, the UNEP (United Nations Environment Program) estimates it at 15 % worldwide (2,940 TWh) for 5% of global greenhouse gas emissions (1,150 million tonnes of CO2). However, despite major advances in terms of energy efficiency, many direct or indirect impacts on our environment, our health, well-being and productivity are not considered, and we can no longer neglect these impacts.

It is then necessary to define a new methodology, which will allow the extension of the classic LCA by taking into account several health and social criteria, in particular regarding the potential ”impacts on human” ( blue light and impacts on circadian rhythms); the "impacts on ecosystems" (light pollution, potential impacts on insects and plants population); the several “uses of light” (residential, commercial, public lighting, etc.); or even "social acceptability on and by the user of the system" (security, comfort, working conditions, etc.). The aggregation of these criteria, with a classic life cycle assessment and a life cycle cost analysis (cumulative cost of a product throughout its life cycle), will give a global vision (economic, social and environmental) of the potential impacts of lighting and will helps to offer a decision support tool for establishing coherent and appropriate strategies around the transformation of our lighting systems.

ECONECT: Developing connected environmental sentinel systems to better understand the degradation of rivers, the decline of bees and birds

Context Presentation

The ECONECT project began in early 2020, with the objective to develop a communication infrastructure allowing the remote monitoring of autonomous, connected, and versatile systems to measure the responses of bioindicator organisms to chemical contamination, habitat degradation and global warming.

Three sentinel systems are considered:(1) the connected hive, allowing to monitor the dynamics of bee colonies (colony mass, temperature and location of the bee cluster, foraging traffic, etc.) and the cognitive capacities of bees; (2) the connected bird-feeder to submit individually monitored tits to behavioral tests to assess their cognitive abilities; (3) the aquacosm, a floating enclosure allowing the measurement of eco-markers in an aquatic environment (growth dynamics of phototrophic biofilms, relative importance of autotrophic and heterotrophic processes within the ecosystem ...).

In 2022, a network of 12 sentinel stations will be deployed in the Zone Atelier Pyrénées-Garonne (PYGAR). Each station will be characterized by a spatial analysis of land use and the quality of habitats and by the measurement of concentrations of chemical contaminants (trace metal elements, PAHs, pesticides) in different compartments of the environment. Participatory science protocols will be used to supplement the available data set and to assist in the interpretation of observed trends, while providing environmental education opportunities for the public.

Impact of spatial strategies of bees on colony performance

Context Presentation

Foraging for food to substantiate one’s needs is of great importance for every species. In the case of bees, who are a social species, only a small selection of individuals has the task to bring the food for the whole colony, and thus has to take into account the needs of the entire population in terms of nutrients. As central place foragers, bees will explore and exploit flowers around their nest, where different species provide bees with different amounts and qualities of nectar. Bees are as a result faced with a complex problem: finding flowers that are not already exploited by other bees, which provide the nutrients in the right amount (either by foraging on a single species of flowers with a balanced diet, or on multiple species with unbalanced but complementary diets), and create a stabilized exploitation route between them. Following each individual bee in its foraging trip has been a technological challenge. However, today, as different tracking technologies (radars, camera tracking) are being developed, assisted with colony monitoring systems (connected hives), we can finally get some insights on these complex behaviors. As data are still scarce and only available in limited, simplified situations, building theoretical models that successfully replicate the spatial strategies of bees will allow us to make predictions on more complex and ecologically relevant scenarios.

Scientific Goals

- Conduct experimental tests for the fundamental hypotheses of the behavior.

- Build a new model based on experimental tests of simple situations and theoretical knowledge of bee foraging behavior.

- Test the model’s predictions in complex environmental situations.

Life Cycle Assessment (LCA) of Lighting Systems: Environmental, Economics and Human Impacts Analysis

Context Presentation

When it comes to identifying and measuring the quantifiable effects of products or services on the environment, Life Cycle Assessment (LCA) is probably the most powerful and recognized tool. Thanks to a multicriterion and a cradle-to-grave approach, LCA identifies and quantifies, throughout the life of products, the physical flows of matter and energy associated with human activities (extraction of raw materials required for the manufacture of the product, distribution, use, collection and disposal to end-of-life systems and all phases of transport). For each of its flows, there are impact indicators that establish the overall potential impact of the system on our environment.

During past years, smart lighting technologies allowed significant improvements regarding lamp efficiency during use phase (from 19% to 15% of global electricity consumption), nevertheless, there are direct or indirect impacts on our environment, health, well-being or productivity not taken into account into Life Cycle Assessment (LCA) studies, and we can’t no longer neglected them.
